What are these core.* files?
Jeroen van Rijn
I am running RH7.1 on an AMD 1.2GHz. In my home directory I frequently
find a big bunch of files, all by the name of core.???? where the
question marks stand for a 4 digit number. It seems one or two files are
created per day.
What is worse is that these files are big! Varying in size from 80 to 577
MB! This is really eating space.
So what are they? Can I just delete them? How can I prevent them?
Any help is appreciated.

IIRC, those are created when a program gives a core dump. I BELIEVE
they are used when sending in bug reports.

These are memory dump files that are created whan a program crashes.
You can delete them.
If you are using the csh or tcsh, you can restrict the size or the creation
at all with limit coredumpsize max-size.

A lot of programs are written to leave a core file when they have
problems. The only one I've come across that leaves core.XXXX files is
xine, a DVD player.
If you are not going to send bug reports with the debugging from the
core, you can remove them at will. Just ensure you are removing the
actual core files and not things like core.h that you do actually need.
If it's in your home directory, you can remove it, though.

if you type the following at your command prompt...
file core.***
this should tell you what program caused the core dump. if you then want
to debug it (i wouldn't advise debugging netscape!), type
gdb netscape core
in the directory your core file was dumped to.
